The tank is built directly upon this floor 2;-a`nd iny the'pr-eferred form includes *a* Apluriality-' oferows or-tiers'l of -hoilow tile 3, standing on end."Each row orV tier ot the'hol- 'low tile 3 is positioned'on top of the' next adjacent rowortienand in staggered orbroken jo'intirelation"thereto, as clearly shown inn 'idFgk2 0fthedrawing.rvr These rowsv ofuhollow` ltilef-are-shown arrangedin t-he torni of a circle' in thedrawinggbut it is to-be under- AStood thatthey maybe-arranged inf='arious r;othei' found-*This "sidewall isbuiltto the Tojthe accomplishment of the `foregoing;z'desiredheijght, as many` rows or tiers of? tile and, such other objects as 'may hereinafter being usedas necessary for this purpose.

Referring now; to the drawings, 1 desig- 'f-the' excavation isfiilled Y with a suitable lquanfitityf of-gra'vel,-cinders or'other suitable fluid;k pervious material.

j"'I-h'einside ofthe ivall and the bottom of the tank-are cemented-'or plastered so as tof be Waterjtight, as indicatedat 4.

v"":Th'e'` discharge from the tank is provided by the construction shown to the left inFig. 1, and in detail in Fig. 5, and includes thepair otfhollow tile members 9 and l-mounted one on topof thefothenthe tiley member 9 being `cementedor-plastered to the insideFof--the Wall ot the tank, as indicated in Fig.l 2; The tile member 10 fits between two tile members ofthe Awallpi the tanlnand has the open' ing 11 formed therethrough which communix kcates'iv'vith theopenings 12 formed in the tile `mem-bers atior about the pointof contact.y1 It is` tobefnoted that-the lower -end 130i the `'discharge conduit formed by the pair 'of tiles i. natesalsutable,excavationavhich is made at" 9pand; 10 is ,slightly above the lower-end of Q thesite.v of the tank." This may be ofzany, de Q ,siredsize in accordance with requirements of 45, use.

- the` inletmember 7 so that the latter issealed at Lallwtimes.

A suitablelid or cover 14 is pr-ovidedy and are preferably formed of copper wire netting and are arranged as indicated in Fig. 2

vsa

so as to assist in the separation of the material within the tank. Y Y

Extending outwardly from the excavation 1 are trenches 16 which may be filled with gravel, cinder, ashes and the like for drain age purposes; and additional trenches radiating therefrom, as indicated at 17, may be provided or made at any time whenever necessary.

The construction designated 5, 6, 7 and 8 not only forms an inlet, butV also provides a tell-tale vent whereby a measuring rod, stick or the like, the depth of the liquid in andthe condition of the tank may be readily ascertained.

As an alternative form, 'and instead of us'- ing hollow tiles, shown in Figs, i1 and 2, I may use the ordinary bricksbuilt in the form of an ideal wall, as illustrated inlFigs. 3. and 4l. The bricks 18 are arranged in rows or tiers staggered, each row or tier consisting in alternation of a pair of bricks arranged longitudinally side by'sideas at 19` and an end brick 20 extending transversely theref across, the bricks all standing on edge., .The

bricks in the next adjacent tier or row are staggered with respect to the previous .tier

or row, whereby an lopen brick wall isconstructed. The rest of theconstruction will be substantially the same. 1

The operation of the device is simple and obvious from al consideration' of this specification and the drawings. passes into the tank from'the inletconnection 5. the solidm'atter settling to the bottom and the liquid passing through the discharge con,- duit 9, 10, out through the yopenings 11, 12, and thence through the oints into the gravel surrounding the tank and the Y trench or trenches radiating therefrom.

in F ig. 1 of the drawings, the tiles 9 andA 10 forming the Ydischarge conduit, ywill be vlo-A cated at a point removed rfrom the top ofthe tank, as willbe the openings orapertures 11, 12. In this instance. the lower end of the inlet 7' will also be located at alower point,v

y this always being at a vslightly lower level than the lower end of the discharge conduit 9 l0.

It isobvious, therefore, that I have provided a septic tank lwhich maybe made and constructed entirely of standard supplies,in

`cludinghollow tiles or bricks, cement, plaster and the like available at any place, and that due to the simplicity of theconstruction, skilled labor is not necessary for erection.V `An important feature isthe broken joint' construction Yof the Yside wall :ofthe tank, which accomplishes better distribution y of the dischargedfluid outside the tank.

' What I claim is y The. lmaterial 1. A septic tank, including in combination, a side wall of open construction" made fluid tight on the inside thereof, an inlet leading through one side of said wall and having the end thereof locateda substantial distance from the top of said tank, and a vent and tell-tale connection extending upwardly from said inlet, a discharge conduit secured to the other side of said tank and having the inlet end thereof located in a plane above the plane of the discharge end of the inlet connection, said discharge conduit l having communication near the upper end thereof with the interior of said open side wall, a'lidor cover for said tank, and a plurality of staggered baiiie screens located in the upper portion of said tank, the lower edges of which terminate below the lower ends of said inlet and discharge connections.
